Amazon has posted a teaser video to YouTube showing customers looking at an unannounced product. The video doesn't show the product or even indicate what sort of product the people are looking at. All it does show is the reaction the customers have to the product.

You can see people call whatever they are looking at awesome, cool, and other things. All we know is that this will be a new device. Speculation suggests that this may finally be the 3D smartphone that has been long rumored from Amazon.

Rumors about the 3D smartphone suggest that it uses tech to create stereoscopic images without the need for 3D glasses. The tech works by tracking the user's eyes and showing them the correct image for each eye. The official launch event for the device will be held on June 18.
